The Orc Ship is highly sought after! It holds the most in Cargo and it does 150% Cannon Damage over the Gargoyle and Tokuno Ships. Therefore it is perfect for use in Pirate PvP and doing more Pirate Bounty Quests.
The only way to get an Orc Ship is to do a Professional Bounty Hunter Quest and accumulate 8 pieces of the Orc Ship to make an Orc Ship Deed.
Upon accepting the quest, a Pirate Bindin' Rope will be placed in your backpack and a Pirate Bindin' Pole will be placed on your boat. You need to search the seas for the pirates and the pirate ships. Your ship's pilot or NPCs around the Sea Market might tip you off about the pirates' location with Pirate locations. Note that pirates are mostly found around Jhelom.
Once you've found a pirate ship, you need to damage it enough in order to board it or cast summon spells on it. If you kill the pirate, a death certificate will be placed in your backpack with the pirates name on it. However, you'll also receive a special reward if you can capture the pirate alive. When the pirate's Hit Points is less than 10%, the Pirate Bindin' Rope can be used on her/him which will chain the pirate on the Pirate Bindin' Pole.
The gold listed on the bulletin board and a special reward from Bigglesby if captured alive: One of the 8 parts of Ruined Ship Plans that can be combined to obtain a Deed for an Orc Ship OR One of the special Cannonballs: Light Flame Cannonball, Heavy Flame Cannonball, Large Flame Cannonball, Light Frost Cannonball, Heavy Frost Cannonball, or a Large Frost Cannonball.
The first orc ship sold on Pacific for 50 Million Gold and I have heard on other shards like Atlantic they are selling for 20 Million Gold Pieces each...!
